FreeBSD 9.2-RC3 发布

FreeBSD是类UNIX操作系统，它基于加州伯克利大学的“4.4BSD-Lite”发行并带有一些“4.4BSD-Lite2”增强，面向i386、amd64、IA-64、arm、MIPS、powerpc、ppc64、PC-98、UltraSPARC等平台。它还间接地基于“386BSD”，此乃William Jolitz对加州伯克利大学的“Net/2”往i386系统上的移植，尽管如今只有极少的代码保留下来。FreeBSD被全世界的公司、因特网服务提供商、科研人员、计算机专家、学生、家庭用户等用于他们的工作、教育、娱乐中。FreeBSD带有20000多个软件包，它们是预编译和打包好了、便于安装的软件，并覆盖了广阔的应用领域：服务器软件、数据库和网页服务器、桌面软件、游戏、网络浏览器和商务软件，而这一切都是免费和易于安装的。

Glen Barber has announced the availability of the third (and likely final) release candidate for FreeBSD 9.2: " The third release candidate builds of the 9.2-RELEASE release cycle are now available on the FTP servers for the amd64, i386, ia64, powerpc, powerpc64, and sparc64 architectures. This is expected to be the final release candidate for the 9.2-RELEASE cycle. Changes between -RC2 and -RC3 include: fix an integer overflow in computing the size of a temporary buffer which can result in a buffer which is too small for the requested operation; revert fixes and improvements to sendfile(2), which uncovered a bug in the NFS implementation that in turn can cause deadlocks; default net.inet.tcp.experimental.initcwnd10 to off."
